GENERAL SAFETY RULES
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions
may result in electric shock, fire and/or serious injury.
Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool”
in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE SAFETY INSTRUCTIONS.
WORK AREA SAFETY
1. Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which
may ignite the dust or fumes.
3. Keep children and bystanders away while operat-
ing a power tool. Distractions can cause you to lose
control.
ELECTRICAL SAFETY
1. Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any adapter
plugs with earthed (grounded) power tools. Unmodi-
fied plugs and matching outlets will reduce risk of electric shock.
2. Avoid body contact with earthed or grounded sur-
faces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your
body is earthed or grounded.
3. Do not expose power tools to rain or wet condi-
tions. Water entering a power tool will increase the risk
of electric shock.
4. Do not abuse the cord. Never use the cord for carry-
ing, pulling or unplugging the power tool. Keep cord
away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric shock.
6. If operating a power tool in a damp location is
unavoidable, use a ground fault circuit interrupter
(GFCI) protected supply. Use of a GFCI reduces the risk
of electric shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a
power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inatten-
tion while operating power tools may result in serious
personal injury.
2. Use personal protective equipment. Always wear
eye protection. Protective equipment such as a respiratory mask, non-skid safety shoes and hearing protection used for appropriate conditions will reduce the risk
of personal injury.
3. Prevent unintentional starting. Ensure the switch is
in the off-position before connecting to power source
and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or
energizing power tools that have the switch on invites
accidents.
4. Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a
rotating part of the power tool may result in personal
injury.
5. Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
5. When operating a power tool outdoors, use an ex-
tension cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of electric
shock.

6. Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving
parts. Loose clothes, jewelry or long hair can be caught
in moving parts.
GENERAL SAFETY RULES
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions
may result in electric shock, fire and/or serious injury.
Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool”
in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE SAFETY INSTRUCTIONS.
7. If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
POWER TOOL USE AND CARE
1. Do not force the power tool. Use the correct power
tool for your application. The correct power tool will
do the job better and safer at the rate for which it was
designed.
2. Do not use the power tool if the switch does not turn
it on and off. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
3. Disconnect the plug from the power source and/or
the battery pack from the power tool before making
any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
4. Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the power
tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained
users.
5. Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before
use. Many accidents are caused by poorly maintained
power tools.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits, etc.
in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
8. Use clamps to secure your workpiece to a stable
surface. Holding a workpiece by hand or using your
body to support it may lead to loss of control.
9. KEEP GUARDS IN PLACE and in working order.
SERVICE
1. Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
CALIFORNIA PROPOSITION 65 WARNING
Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities may contain
chemicals, including lead, known to the State of California to cause cancer, birth defects, or other reproductive
harm. Wash hands after handling. Some examples of
these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement, and other
masonry products.
• Arsenic and chromium from chemically treated
lumber.
Your risk from these exposures varies depending on
how often you do this type of work. To reduce your exposure to these chemicals, work in a well-ventilated area
with approved safety equipment such as dust masks
specially designed to filter out microscopic particles.
SPECIFIC RULES FOR YOUR MITER SAW
WARNING! Do not operate the power tool until you have read and understood the following instructions
and the warning labels.
SAW BLADE SAFETY
1. Always wear protective gloves when handling saw
blades.
2. Only use blades with correct size and type for both
your miter saw and your workpiece.
• The rated diameter of the saw blade is 10 inches
with a 5/8 inch arbor.
• The no-load speed of the Miter Saw is 4500 RPM.
The maximum permissible speed of your saw blade
should always be higher than the no-load rotational
speed of the saw.
3. Never use damaged or deformed saw blades. Only
use sharp blades.
4. Install the saw blade in the correct orientation indicated in the instructions (see "Changing The Saw Blade"
on page 17).
5. Keep hands out of path of saw blade. Never use your
hands to remove sawdust, chips or workpiece near the
saw blade or the cutting path of the saw.
3. People with pacemakers should consult their
physician(s) before use. Electromagnetic fields in close
proximity to pacemakers could cause pacemaker interference or pacemaker failure.
4. Wear work gloves when handling saw blades. DO
NOT wear gloves while operating the saw.
5. Sawdust is harmful to your health. Use NIOSH-approved dust masks or other respiratory protection during operation and cleaning.
6. Always turn off and unplug the miter saw before making any adjustments or repair tasks. Never adjust the
miter saw or the workpiece while the saw is running.
7. Never use damaged or incorrect blade flanges or bolt.
The blade flanges and bolt were specially designed for
your saw, for optimum performance and safety of operation.
8. Do not use to cut metal, logs, tree limbs, or uneven
lumber. Inspect the workpiece and remove all nails and
other embedded objects prior to starting work.
6. Never reach around saw blade or reach in back of the
saw blade.
7. Do not use blades made from high-speed steel, abrasive blades, metal-cutting blades or masonry-cutting
blades. The guards of this saw are not designed to protect against the failure of such blades.
8. The use of accessories or attachments not recommended by the manufacturer may result in a risk of personal injury.
PERSONAL SAFETY
1. Operate in a well ventilated area. Keep the floor area
around the miter saw level and free of slippery substances or other tripping hazards.
2. Wear ANSI-approved safety goggles to protect your
eyes from sparks and sawdust. Use hearing protection
to protect yourself from hearing loss.
9. Wet lumber, green (unseasoned) lumber, and pressure treated lumber all have an increased potential for
kickback and should only be cut with a blade specifically
designed for that lumber type. Wear a NIOSH-approved
respirator and have appropriate ventilation whenever
cutting pressure treated lumber.
PREPARING THE MITER SAW
When transporting the miter saw, carry it by either the
handle or the base. Never carry the device by its guards
or its accessories. Make sure that the blade is fully covered by the blade cover and not exposed.
1. Examine the miter saw for any damaged or missing
parts. Replace or repair damaged parts before operation. Periodically check that all nuts, bolts and other fasteners are properly tightened.

SPECIFIC RULES FOR YOUR MITER SAW
SECURE YOUR WORKPIECE
1. Never hand-hold a workpiece that is too small to be
clamped, as it can be launched away and cause injury. Use proper support and guides to secure the small
workpiece.
DURING CUTTING OPERATIONS
1. Always stand to one side when operating the saw.
Never have any part of the body in line with the path of
the saw. Never hold a workpiece in your hand or across
your legs while cutting.
2. Ensure hands are away from the cutting area and
blade. Keep one hand on the operating handle, and the
other out away from the blade and its path.
3. Feed work into the blade against the direction of rotation of the blade only.
4. If you are interrupted when operating the saw, complete the process and switch the saw off before looking
up.
9. Never cut more than one piece at a time. Do not stack
workpieces together. Do not attempt to cut material
thicker than specified on page 2 of this manual. Adjust
the cutting depth to the thickness of the workpiece (less
than a full tooth of the blade should be visible below the
workpiece).
10. If a cut does not extend to the edge of the workpiece,
or if the blade binds in the cut, allow the blade to come
to a complete stop and lift the saw out of the workpiece.
11. Turn off tool and wait for saw blade to stop before
moving workpiece or changing settings. Do not slow or
stop a blade with a piece of wood. Let the blade come
to rest naturally. Do not attempt to free a jammed blade
while the machine is still running and connected to
power.
12. Always raise the blade to be covered by the blade
guard after use.
LASER SAFETY
5. Power tools must always be held by the insulated
gripping surfaces when performing an operation, ensuring protection if the cutting tool makes contact with
its own cord or hidden wiring. Contact with a ‘live’ wire
will make exposed metal parts of the power tool ‘live’
and shock the operator if the insulated gripping surfaces are not used.
6. Do not use the miter saw unless all guards are in
place. Do not operate with any guard disabled, damaged, or removed. Moving guards must move freely and
close instantly.
7. Turn on the miter saw and let it reach full speed, then
slowly slide the saw into the workpiece. This will help
produce safer and cleaner cuts.
8. Always push the saw blade forwards and away from
you. Do not pull the saw towards you, or move the saw
backwards while cutting. Do not apply any sideways or
twisting force to the blade while cutting.
ATTENTION: LASER RADIATION. Class 2 laser.
DO NOT STARE INTO THE BEAM
1. Do not look directly into the laser beam with unprotected eyes. Never look into the path of the beam.
2. Never point the laser beam towards reflecting surfaces. Never point the laser towards people or animals.
Even a laser beam with a low output can cause damage
to the eyes.
3. Never open the laser module as unexpected exposure
to the beam can occur. The laser cannot be replaced
with a different type of laser.
4. Repairs of the laser may only be carried out by the
laser manufacturer or an authorized representative.

ELECTRICAL INFORMATION
DOUBLE-INSULATED TOOLS
The tool’s electrical system is double-insulated where two systems of insulation are provided. This
eliminates the need for the usual three-wire grounded power cord. Double-insulated tools do not need
to be grounded, nor should a means for grounding be added to the product. All exposed metal parts
are isolated from the internal metal motor components with protecting insulation.
IMPORTANT: Servicing a double-insulated product requires extreme care and knowledge of the system, and
should be done only by qualified service personnel using identical replacement parts. Always use original factory
replacement parts when servicing.
1. Polarized Plugs. To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider
than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse
the plug. If it still does not fit, contact a qualified electrician to install a proper outlet. Do not modify the machine
plug or the extension cord in any way.
2. Ground fault circuit interrupter protection (GFCI) should be provided on the circuit or outlet used for this power
tool to reduce the risk of electric shock.
3. Service and repair. To avoid danger, electrical appliances must only be repaired by a qualified service technician
using original replacement parts.
GUIDELINES AND RECOMMENDATIONS FOR EXTENSION CORDS
When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An
undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. The table below shows
the correct size to be used according to cord length and ampere rating. When in doubt, use a heavier cord. The
smaller the gauge number, the heavier the cord.
AMPERAGE
25 ft. 50 ft. 100 ft. 150 ft.
15A 14 gauge 12 gauge Not Recommended
1. Examine extension cord before use. Make sure your extension cord is properly wired and in good condition.
Always replace a damaged extension cord or have it repaired by a qualified person before using it.
2. Do not abuse extension cord. Do not pull on cord to disconnect from receptacle; always disconnect by pulling
on plug. Disconnect the extension cord from the receptacle before disconnecting the product from the extension
cord. Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
3. Use a separate electrical circuit for your tool. This circuit must not be less than a 12-gauge wire and should
be protected with a 15A time-delayed fuse. Before connecting the motor to the power line, make sure the switch
is in the OFF position and the electric current is rated the same as the current stamped on the motor nameplate.
Running at a lower voltage will damage the motor.
